Narrative:

En route from aus to crq with fuel stop dmn. Received and copied rerte instructions. On V458 wbound west of ipl VOR and east of kumba intersection. Started right turn to join V458 too early, was not yet at kumba intersection. The mistake was brought to my attention by ZLA. I thought my DME was set to read off of the #1 navigation radio, but it was actually reading off of the #2 navigation radio, which was tuned to a different VOR. ATC advised that R2510A and kane south MOA were in my route of flight and that MOA was 'hot.' single pilot operation, inoperative autoplt, and 6 hours flying time (2 1/2 in IMC), along with pilot fatigue and unfamiliarity with geographic area were contributing factors. I was trying to make unfamiliar airport while still daylight to keep appointment with a customer.
